Apple III © 1980 Apple Computer Company.
The Apple III is a business-oriented personal computer produced and released by Apple Computer that was intended as the successor to the Apple II series, but was largely considered a failure in the market.
Development work on the Apple III started in late 1978 under the guidance of Dr. Wendell Sander. It had the internal code name of 'Sara', named after Sander's daughter.
The machine was first announced and released on May 19, 1980, but due to serious stability issues that required a design overhaul and a recall of existing machines, it was formally reintroduced in the second half of 1981.
